ENHANCED MAGNETIC VIBRATION DAMPER WITH MECHANICAL IMPEDANCE MATCHING

摘要

Magnetic vibration damper includes three coaxial elements: a first coaxial element with first permanent magnets, a second coaxial element with first soft magnets and a third coaxial element with second permanent magnets. The first soft magnets are located between the first permanent magnets and the second permanent magnets in a radial direction. The spacing of the second permanent magnets is larger than the spacing of the first permanent magnets. The damper further includes an energy conversion component, such as conductive layers or coils to convert the mechanical movement of the magnets into heat or electric current.

1. Magnetic vibration damper comprising a first coaxial element, a second coaxial element, at least a third coaxial element and energy conversion means configured to dissipate mechanical energy, being the first coaxial element, the second coaxial element and the at least one third coaxial element mechanically configured to enable relative movements along a common axis, wherein:
the first coaxial element comprises at least a plurality of first permanent magnets equally spaced along the axis direction; the second coaxial element comprises at least a plurality of first soft magnets equally spaced along the axis direction; the at least one third coaxial element comprises at least two second permanent magnets, and the at least a plurality of first soft magnets being located between the at least a plurality of first permanent magnets and the at least two second permanent magnets in a direction perpendicular to the axis direction.
